Abstract

Our hypothesis was that the horseshoe crab ventral eye functions in place of equilibrium receptors in sensing when the animal is upside down. The juvenile organs had fewer photoreceptors (adult size) and reflective guanine crystals, as in adult lateral eyes (dissections and histological sections). Juveniles buoyed to float upside down crawled and burrowed normally on and in a floating wax-bead "beach", but turned over when their ventral eyes were illuminated.
